are attached to the base 30 and bear upon the upper edges of theOperating levers 1, 2, 5 and 6 respectively.

The type blocks 9 and 10 each carry rigidly attached to their undersurface three printing elements or types arranged as shown in Fig. 2.Printing elements 1', 2 and a are each divided into four arbitrary unitsof length while printing element 3 is, when measured lineally along thetype block 10, four of these arbitrary units in length.

Type element 2 is spaced on type block 9.

as shown a distance of two units of its length removed from type element4*, while type element 6 is spaced on type block 9 a distance of fiveunits away from type element 1- Type element 1 is spaced on type block10 a distance of one unit of its length away from type element 3 whiletype element is spaced a distance of six units from type element 3 Typeblocks 9 and 10 are carried on the operating levers 1, 2, 5 and 6 insuch relation to each other that type element 3 is separated lineallyfrom type element 4* by one unit of type element length.

A. prism-shaped anvil 27 is placed opposite the type blocks 9 and 10 andpresents three printing faces to the printing elements. A screw 28serves to adjust the anvil in its distance from the printing types.

A tape 27 sensitized with any chemical compound for electrolyticprinting, rests on the surface of the anvil and is carriedlongitudinally over the printing faces of the anvil by means of the setof rollers as shown.

A form of transmitter is shown at the right of Fig. 1 and comprises apair of direct current dynamos 17 and 18 or other source of current,their terminals of opposite polarity being connected together and toground 26, while the positive terminal of dynamo 18 is connected tobrushes 19 and 19 and the negative terminal of dynamo 17 is connected tobrushes 19 and 19 A flexible brush 20 is of sufficient width to bearupon both brushes 19 and 19 and make contact therewith. A brush 21 is ofsuflicient width to bear upon both brushes 19 and 19 and make contacttherewith. Brushes 20 and 21 are connected to line conductors 24 and 25respectively and are normally held out of contact with their adjacentpairs of brushes by transmitting tape 29.

It will be noted that by a proper transverse spacing of the perforationsin the transmitting tape 29 with respect to brushes 19 and 19 a positiveor negative impulse may be sent over line conductor 24: throughelectromagnets 11 and 16 to ground, thereby as hitherto noted reversingthe polarity of one of the magnets of that pair from its normal polarityinduced by" the field solenoid 23 and cause the release of itsrespective operating lever which under spring tension rotates type block9 or 10 as the case may be, dependent upon the polarity of the operatingimpulse, to bring either printing type 1 or 6 into contact with therecording tape 27. By a proper transverse spacing of the perforations intape 29 with respect to the brushes 19 and 19 a positive or negativeimpulse may be sent over line conductor 25, through electromagnets 12and 15 to ground to cause the release of either operating lever 2 or 5to rotate type block 9 or 10 to bring type element 2 or 5 into contactwith the recording tape 27. A positive impulse over line conductor 25and a simultaneous negative impulse over line conductor 24. will operateoperating levers 1 and 5 to carry type block 10 downward with a movementof translation to bring type element 3 into contact with the recordingtape 27, while a positive impulse over line conductor 24 and asimultaneous negative impulse over line conductor 25 will operateoperating levers 2 and 6 to move type block 9 downward to bring typeelement 4: into contact with recording tape 27. Thus it will be observedthat by a predetermined transverse spacing and grouping of theperforations in transmitting tape 29, either type block 9 or 10 may berotated to imprint its type element borne near its extremities or eithertype block may be moved downward substantially without rotation toimprint the type element borne near its middle portion.

Referring to Fig. 2 which may be considered to be an enlarged view ofthe impressions of the type elements as they would appear were all ofthe types imprinted on a motionless receiving surface, types 1, 2 3 andr are each in length equal to the width of a complete normal charactersuch as H. The width of a complete normal character is divided into fourarbitrary units, while the types are separated from each otherlongitudinally by one of these units as has been hitherto explained.

Fig. 5 shows a sectional transmitting tape 29 perforated to send all oiithe characters necessary to transmit intelligence in the Roman alphabet.The longitudinal lines -1, +6, 2, and +5 correspond to the lines ofcontact of the brushes 19', 19 19 and 19 with the brushes 20 and 21. Thetransverse lines are spaced a distance apart equal to or proportional tothe unit of length of the printing elements 1, 2 3 and 1 dependent uponthe ratio of the speed of the transmitting and receiving tapes. Thus aperforation along the line 1 in the transmitting tape 29, will cause theimprinting of type element 1, while a perforation along theline +6 willimprint type element 6. A perforation along the line 2 will imprint typeelement 2 and a perforation along the line +5 will imprint type element5". Perforations along the lines +1 and +5 and opposite each other willimprint type element 3 while perforations along the lines -2 and +6 andopposite each other, will imprint type element l Conceive now the tape29 to move from right to left as viewed in Fig. 5 between thebrushes20and 21, and 19, 19 19 and 19 of Fig. 1 at a speed which allows one.

sending simultaneous positive impulses of current over line conductors24; and 25v through magnets 15 and. 16 counterclockwise to releaseoperating levers 5 and 6 to rotate type blocks 10 and 9 respectively tosimultaneously imprint types and 6 upon the recording tape27, and aftertape 29 has moved through the transmitting brushes adistance of fourtape intervals, a slmllarly.

placed pair of perforations allow contact to bemade through the samebrushes as before with line conductors24 and 25, again sendingsimultaneous, positive impulses counter clockwise through magnets 16 and15, again imprinting type elements 5 and 6 on the recordin tape 27 adistance away from the previous imprints of four units, or the width ofa normal character.

pair of perforations placed along the lines --2 and +6 and opposlte eachother, allow a negative lmpulse of current and a positive impulse ofcurrent to be simultaneously sent over conductors 25 and. 24:respectively,

through magnets 12 and 16, thus cruising operating levers 2 and 6 :tomove type block 9 vertically downward to imprint type element 4* on therecording tape 27. This imprint abuts at its extremities the two previous sets of-imprints as these two imprints have been carried by thereceiving tape a distance of five units of tape length, previous to theimprinting of type element 4*. After the transmitting tape 29 has passedthrough the brushes ofthe transmitter, a

distance of six tape intervals, a perforation along the line 1 allows anegative impulse of current to be sent over line conductor 24 throughmagnet 11 in a counterclockwise direction to imprint pen face 1 which asthe previousimprints' on -the receiving tape 27 have been carried fromright to left a distance of six units of width since the last imprintallows the extremities of the imprint of type element 1 to abut at itsextremities, the previous imprints of After tape 29- has passed throughthe transmitting brushes a distance of five tape intervals, a.

type element 5 thus forming the letter A as shown. in Fig. 5. Thecharacters are separated from each other on the recording tape by adistance of four tape units or the length of a. complete normalcharacter. Thus in imprinting the character B after imprinting thecharacter A, the left hand vertical ofletter B is imprinted byperforations along the lines +5 and +6.0pposite each other and adistance of four tape intervals from the perforations which cause theimprinting of" the right hand vertical of letter A. This causes anoverlapping of the sets of perforations in the transmitting tapefor aseries of characters, The spacing between any two characters is providedin the transmitting tape preceding the letter or'character to beimprinted as in the case ofthe letter D which is a double spaced letteror'twice the width of a normal character; The perforations to imprintthe left which cause the imprinting ofthe right hand vertical of theprevious characterfas the character D to distinguish it from thecharacter O is provided with an imprint from type element 2 which causesit to become *a double spaced character with the normal spacing betweenit'and the prevlously 1mprlnted character of the chosen four units of.length of a normal character. Similarly vall of the'characters necessaryto transmit intelligence in the Roman alphabet may be recorded.
